GE PDE9900 manual Single Rack WashTM, Normal Wash Cycle

Single Rack WashTM

The Single Rack WashTM bypasses the lower spray arm, directing the water flow only to the upper rack. A plastic-covered steel ball, released by a wax motor-controlled magnet, is forced by the water flow to block the venturi for the lower spray arm. Cleaning power is directed to the top basket ONLY through the middle and upper spray arms. In Single Rack WashTM, the tub fills with approximately 0.1 to 0.2 gals. less than a normal wash cycle.

Normal Wash Cycle: The pump fills with water to the level indicated. The magnet on the end of the wax motor holds the ball out of the water flow path. The impeller spins counterclockwise to a high velocity. Water flowing from the impeller outward, fills all chambers.

Single Rack WashTM Cycle: The pump fills with water to the level indicated. At the same time, the wax motor energizes and pulls the magnet away. This releases the ball from its position at the bottom of the guide rail.

The impeller spins counterclockwise to a high velocity. The water flows from the impeller and carries the ball up the guide rail. The ball wedges into the low-arm channel restricting the flow from the lower spray arm. The water flow is now diverted to only the upper and middle spray arms.
